Laser Emitting conditions:
1) When the Top Cover is removed, and the “STANDBY/ON” SW is turned to the "ON" position, the laser component will
emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through
the lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser
emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB. However, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.

W*
* This output is the value measured at a distance of about
200 mm from the objective lens surface on the Optical
Pick-up Block.
When checking the laser diode emission, keep your eyes more
than 30 cm away from the objective lens.
